COAL OR ORE JIGGER AND WASHER.

SPECIFICATION forming part of Letters Patent No. 481,438, dated August 23, 1892.

Application filed March 29, 1892. Serial No. 426,911. (No model.)

To aZZ whom it may concern:

Be it known that I, SEBASTIAN STUTZ, a citizen of United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Coal or Ore J iggers and Washers; and I do hereby declare the following to be a full, clear, and exact de scription of the invention, such as willenable others skilled in the art to which it appertains to make and use the same.

This invention relates to coal or ore jiggers or washers.

The object of the present invention is to produce an ore or coal jigger or Washer whereby by a simple construction both coarse and fine impurities may be collected in an auxiliary reservoir below the washer, from which they can be discharged at will.

Furthermore, the object of the invention is to produce a coal or ore jigger or washer in which the plunger or piston for forcing the water through the coal or ore is provided with openings at the bottom, governed by floating valves properly guided, and by which arrangement the place below the piston or plunger is always filled up by the water.

With these objects in view the invention consists in a coal'or ore washer orjigger comprisinga separating-chamber, a sieve or screen arranged in said chamber, a slate-chamber adjacent to the separating-chamber, a piston or plunger chamber, a piston or plunger reciprocating vertically in said chamber, and an auxiliary receiver arranged below the washer and communicating with both the separatingchamber and the slate-chamber. Furthermore, the invention resides in various novel details of construction, whereby the objects of the invention are attained.

The invention is illustrated in the accompanying drawings, in which Figure l is a longitudinal vertical section of a coal or ore washing machine, taken on the line 1 y of Fig. 2, constructed in accordance with my invention. Fig. 2 represents a vertical cross-section at the lines 00 as and z z of Fig. 1. Figs. 3 and 4 are vertical sections at right angle through the plunger or piston, and Fig. 5 is a plan View of the same.

In the drawings, A represents brackets, preferably of cast-iron, upon which is supported a rectangular boX divided into chambers B, O, and H, and constituting two entire machines. Arranged within the chamber 13 is a screen or sieve S, while the chamber 0 contains the piston or plunger P, with its mechanism, to reciprocate vertically.

H represents the slate-chamber, which communicates at its upper end with the separating or washing chamber B through an opening 0, governed by a suitable valve 2'.

F shows a trough or chute provided with a screen I) and communicating with the separatin -chamber B to receive the washed coal as it passes from the latter.

Beneath the slate-chamber H and the separating-chamber B an auxiliary receiver M is arranged, which communicates with both chambers by means of the openings 6 and e e, for the purpose of receiving the coarse and fine impurities. The object of this auxiliary receiver M is to prevent the great waste of water while letting escape the impurities, and thus make the machine do its work continuously, since by previously closing the gates g g and i the water-level cannot sink below the delivery-bridge m; hence the separation is not interrupted. The receiver M is provided with an outlet door or gate D, connected with the levers Z Z by means of a link (I. The gates g g are also connected with the levers Z Z by means of a rod 11. For the purpose of giving the gates g g a certain lead or advance while closing and before the movement of the lever Z is transmitted to the door D, the link d is provided with a slot. A single movement of the levers will effect the closing of the gates g g and the discharge from the machine of both coarse and small impurities.

The piston or plunger P is provided with openings 0 O in its bottom. These openings are governed by floating valves L L, supported upon vertical guides q q, depending from and secured to cross-pieces q q of the piston or plunger P. The object of the improved piston or plunger is to allow the necessary volume of water to enter the machine from above the plunger by means of a pipe W, instead of below, as formerly, and thus fill up the entire space when the piston is moving upward. The inflow of water into the machine through the piston or plunger is further controlled by means of a series of both the separating-chamber and the slatethe plunger-rod near the lower end thereof is a collar 8. This collar is designed to limitthe downward movement of the plunger-rod by engagement with a buffer, in which is seated a spring s, encircling the plunger-rod, the purpose of which is to impart a differential movement thereto.

vented by the water in the plunger-chamber, which otters a resistance to the downward stroke of the plunger, and thereby causes it to descend gradually.

shaft 15 by means of the cam 0, yoke 12 and rod a.

Goal to be washed is supplied to the screen S through the hopper or feed-channel 7c. The pulsations of the water, caused by the movement of the plunger, raise and spread the material out over the whole surfaceof the.

to an elevator E or other receiver, while the heavier material (slate and sulphur) pass through the opening 0 into the slate-chamber H, and thence through 6 into the receiver M During the operation of the machines the gates g g are left Wide open and to the outside.

to allow the sediment of fine sulphur and slate passing'through the meshes of the sieve to enter freely into the receiver M, the front door D of which being tightly closed. The

slate valve or gate 2', governing the opening 0 between the slate-chamber and the separating-chamber, may also bepartly left open to allow the impurities to pass off continuously; or it may be kept closed and opened only at intervals. Before letting the impurities out of the receiver M the gate 1; must be closed to prevent-the water above the screen from escaping; thence the lever Zispnlled upward, thus closing the openings e eand opening the door D of the receiver.

I do not wish to be understood as claiming herein a coal or ore washer or jigger comprising a separating-chamber, a piston or plunger reciprocating vertically therein, a slate-chamber adjacent to the separating-chamber, and an auxiliary receiver arranged below the separating-chamber and communicating with chamber, as this forms the subject-matter of my pending application, Serial No. 423,581, filed March 3, 1892.

Having thus fully described my invention,

The sudden and sharp Y contact of the collar 3 with the butter I is pre-v what I claim as new, and desire to secure by Letters Patent, is-- V 1. A coal or ore washer comprising a separating-chamber, a sieve or screen fitted into the chamber, a piston or plunger chamber adjacent to the separating-chamber, a piston or plunger adapted to reciprocate vertically in said chamber, a slate-chamber adjacent to the separating-chamber, and an auxillary receiver arranged below the bottom of the washer and communicating with both the separating-chamber and the slate-chamber, substantially as described.
